摘要:

eXTP(增强型X射线定时和偏振测量)任务是中国科学院(CAS)和中国国家航天局(CNSA)的一个重大项目,目前正在进行扩展的A阶段研究,并计划于2025年在低地球轨道上发射。eXTP科学有效载荷设想了一套仪器(光谱聚焦阵列,偏振聚焦阵列,大面积探测器和宽视场监视器),提供前所未有的同时宽带X射线计时和偏振灵敏度。一个大型欧洲财团正在为eXTP研究做出贡献,预计将提供关键的硬件元件,包括宽场监视器(WFM)。用于eXTP的WFM仪器基于最初在欧空局范围内为LOFT任务提出的设计。eXTP/WFM设想通过大面积硅漂移探测器技术实现2-50 keV能量范围内的宽场X射线监测系统。WFM将由3对编码掩模摄像机组成,零响应时的总组合视场(FoV)为90 x180度,源定位精度约为1弧分。在本文中,我们提供了一个概述的WFM仪器的设计,包括新的元素与早期的LOFT配置,和预期的性能。

英文摘要:

The eXTP (enhanced X-ray Timing and Polarimetry) mission is a major project of the Chinese Academy of Sciences (CAS) and China National Space Administration (CNSA) currently performing an extended phase A study and proposed for a launch by 2025 in a low-earth orbit. The eXTP scientific payload envisages a suite of instruments (Spectroscopy Focusing Array, Polarimetry Focusing Array, Large Area Detector and Wide Field Monitor) offering unprecedented simultaneous wide-band X-ray timing and polarimetry sensitivity. A large European consortium is contributing to the eXTP study and it is expected to provide key hardware elements, including a Wide Field Monitor (WFM). The WFM instrument for eXTP is based on the design originally proposed for the LOFT mission within the ESA context. The eXTP/WFM envisages a wide field X-ray monitor system in the 2-50 keV energy range, achieved through the technology of the large-area Silicon Drift Detectors. The WFM will consist of 3 pairs of coded mask cameras with a total combined Field of View (FoV) of 90x180 degrees at zero response and a source localization accuracy of ~1 arcmin. In this paper we provide an overview of the WFM instrument design, including new elements with respect to the earlier LOFT configuration, and anticipated performance.
